Ohhhh! I have never managed to learn that, thanks for letting me know, and the certain NPCs you can temporarily transform have a chance to knock the PC up? (Even if not...this is some big news for me. :$)
(Also might I interpret your 'yet' as there is a good chance you'll add some at a point in the future?)
Thanks for your reply, I gonna start a new game right now, seems as if I missed out on (quite?) some stuff, potentially. :D
